CHAIN-WORK FOR JEWELRY.

SPECIFICATION forming part of Letters Patent No. 250,020, dated November 22, 1881.

Application filed May 21, 1851. (No model.)

To all whom it may concern:

Be it known that I, EMILE VIEILLE, of the city and county of Providence, Rhode Island, have invented a new and useful Improvement in Chain-Work for Jewelry, of which the following is a specification.

Figure 1 is a perspective view of a portion of my improvement enlarged. Fig. 2 is a crosssection of the same, taken through the linear m, Fig. 1. Fig. 3 is a plan view of a portion of the chaiirwork; and Fig. etis a cross-section of the same, taken through the line y 9 Fig. 3.

Similar letters of reference indicate correspondin g parts.

The objectof this invention is to secure crossbars in jewelry chain-work without solder.

Theinvention consists in constructing chain- Work for jewelry of interlaced spirals having cross-bars inserted in every other spiral, and bending or folding the side edges of the chainwork down upon the body of the said chainwork, whereby polished cross-bars can be used and firmly secured in place without being heated, as will be hereinafter fully described.

The chain-work is formed by turning or screwing the coils of spiral wires A into each other, the said spirals being made of a length equal to the desired width of the chain-work.

Oross-barsB arethen passed through every 0 other spiral A, as shown in Figs. 1 and 2. The bars B are made of an equal length with the spirals A. The side edges, 0, of the chainwork are then bent or folded over upon the body of the said chain-work,'as shown in Figs. 35 Sand 4. The folding over of the edges 0 gives a finish to the chain-work and fastens the cross-bars B securely in place, so that the said side bars do not need to be secured by solder. This construction enables the work- 40 man to use polished cross-bars B, as they do not require to be heated by soldering, the said heating destroying the polish, which cannot be again restored.

Having thus described my invention, Iclaim 5 as new and desire to secure by Letters Patent Chain-work for jewelry, formed of interlocking spiral wires A and cross-bars B in every othercoil, the side edges, 0, of said cross-bars 0 and wires being folded over the body of the chain-Work, whereby soldering is rendered unnecessary, and polished cross-bars may be employed, as described.
